Pivot Bearing Replacement FDB 300 / FDB 340
Early FDB units can be identified by their lack of radial and axial
tapped holes for the pivot bearing keying dowel (see Figure). Dur-
ing maintenance of these units the customer should replace the
entire rear housing assembly to upgrade the deburring tool. The
early style of pivot bearing and rear housing are not currently sup-
ported.
1 Remove the brass plug or hex socket screw from the center of
the deburring unit's rear housing.
2 Remove the socket head screws securing the rear housing to
the deburring tool's front housing.
3 Remove the rear cover complete with the pivot bearing. Re-
tain the small o-ring and dowel pin between the cover and
housing for reuse if desired.
4 The new rear housing assembly will be provided with new fas-
teners and a new o-ring. Reassembly is the reversal of the
previous steps with the following points:
Insure the dowel pin and small o-ring that go between the
housing and the rear cover are in place before refitting the
rear cover.
Use liquid thread locker on all the socket head screws, but
NOT on the brass pivot post plug (where applicable).
Insure that the spindle air supply fitting is centered in the
housing (side boot) opening prior to tightening the fastener
in the pivot bearing post.
